I am posting here roto and misc  I am needing some type of ball suggestion from storm or rotogrip.  i am a 18 year old bowler bout 18-19mph  with above average revs even if i try to come up the back of the ball as much as possible.  i am having trouble with flying backends.  I have all three of the deuce and reloaded with pins above ring finger and cg and mb kicked out to the right with balnce holes.  original x with pin right and stacked.  epp with pin above and everything kickd out  core power lrg drilled pin 1" above pap with cg and mb kicked left to about 8:00 and a thunder flash 1" pin pin and cg in palm.  i am needing a suggestion on a ball and a drilling to tame backends because even the lrg has more of a tendency to hook at the end even with the way its drilled thanks in advance for your help
